I was just browsing the mod page, looking at some mods to pass the time, and I found something cool. You can now use Halo Weapons and Armour, all thanks to the brilliant mind of ShyKiller15.
They have added a Halo armoury named Halo UNSC Armory V2 today. And with their armour mod SpartanArmorCollection Port from nexus, that have now made a Spartan Playthrough now available.
Thanks again to ShyKiller15 for making these mods and for allowing fans of the Halo series to have some fun on PS5.
